<h2>Import SeaDAS Track Data</h2>

<p>
    As another special case of CSV import,
    the Sentinel Toolbox supports the import of  
    <object classid="java:org.netbeans.modules.javahelp.BrowserDisplayer">     
        <param name="content" value="http://seadas.gsfc.nasa.gov/">
        <param name="text" value="<html><u>SeaDAS</u></html>">
    </object>
    (<b>Sea</b>WiFS <b>D</b>ata <b>A</b>nalysis <b>S</b>ystem) ship track data.
    SeaDAS is a comprehensive image analysis package for the processing, display,
    analysis, and quality control of ocean color data. It has been developed within the
    NASA SeaWiFS (<b>Sea</b>-viewing <b>Wi</b>de <b>F</b>ield-of-view <b>S</b>ensor) Project.
    Note that the Sentinel Toolbox only supports the import of track data generated with the SeaDAS versions 6.x.
</p>
<p>
    In principle, these ship track files are also CSV files, but have an extremely simple layout with three columns only:
    The first two columns contain the vertex points latitudes and longitudes, respectively, and the third column
    gives the values of a single data quantity (such as a ship-based radiometer measurement). These files contain
    <b>no</b> header, all numbers are separated by the 'tab' character.
</p>
